Smart and Sustainable Design for Health and Wellbeing

• Format: ePub

Produktbeschreibung

Building Services Engineering: Smart and Sustainable Design for Health and Wellbeing covers the design practices of existing engineering building services and how these traditional methods integrate with newer, smarter developments. These new developments include areas such as smart ventilation, smart glazing systems, smart batteries, smart lighting, smart soundproofing, smart sensors and meters. Combined, these all amount to a healthier lifestyle for the people living within these indoor climates. With over one hundred fully worked examples and tutorial questions, Building Services Engineering: Smart and Sustainable Design for Health and Wellbeing encourages the reader to consider sustainable alternatives within their buildings in order to create a healthier environment for users.
